As we ground-dwellers go about our daily lives we never give a thought to the crew zipping over our heads 15 times a day in the International Space Station, let alone what happens on the world's surface during every 90-minute spin the astronauts take around the globe. The figures are astonishing. For instance, every time the station completes a full spin of the Earth, the Amazon rain forest has shrunk by an area the size of 300 football fields. Also, 23,029 babies have been born and 9696 people have died. Now there's a disparity. No wonder that since Yuri Gagarin was first blasted into orbit a little over 50 years ago, the world's population has doubled.
Gagarin was of course the first to get a glimpse of how we look from a distance. "The Earth is blue," he exclaimed, "how amazing!".
More amazing to us is the thought that before then, our parents had no clue the Earth was blue. Back then, suddenly, the human race's perspective on the world had changed forever.
As the script says, "We thought we were going to explore the universe, yet the most extraordinary thing we discovered was our own home planet, the Earth."
"NASA doesn't tend to hire many philosophers," said someone in the soundtrack, "but everyone they send up there soon becomes one."
I looked up the production company that made this documentary - and English group called Burning Blue Media. Sadly, it seems to be no more. Its website no longer exists. It's a shame - I was eager to see what else they'd produced. Too ahead of their time, maybe?
